Release Notes: The transport protocol implementations for IP have been refactored so they can support IPv4 and IPv6 connections. The LTE module has been reworked, with new LTE radio protocol models and an EPC data plane model. New propagation models and a buildings pathloss model have been added. An antenna module, which includes different radiation pattern models, has been added. The Random Early Detection (RED) queue model from ns-2 has been ported. A Dynamic Source Routing (DSR) protocol model for IPv4 has been added.
Release Notes: In the mobility module, a new MobilityModel::GetRelativeSpeed() method returns the relative speed of two objects. A new Ipv6AddressGenerator class has been added to generate sequential addresses from a provided base prefix and interfaceId. (It will also detect duplicate address assignments.) TcpHeader now recognizes ECE and CWR flags. Nagle's algorithm is now supported. Various bugfixes and other minor enhancements have been added.
Release Notes: SpectrumChannel models now support the usage of single-frequency propagation loss models based on the PropagationLossModel class. The attribute system was extended to store map container objects in addition to vector containers. Support for IPv4 fragmentation has been added. Numerous bugs were fixed.
Release Notes: Improved support for IPv6 and ICMP. Numerous bugfixes and minor enhancements.
